This fixes errors: ``` File ...hpilo_fw.py, line 32, in config parser.readfp(io.StringIO(conf)) ^^^^^^^^^^^^^ AttributeError: 'ConfigParser' object has no attribute 'readfp'. Did you mean: 'read'? ``` because ConfigParser's `readfp()` is deprecated.

This will add Alpine Linux (tested 3.x) support.
